Where on the balcony picturesque flowers, decorative leaves and bright red fruits draw the viewer into the spell, strawberries in the flower box do the honors. In fact, the seductive fruit plants are not limited to growing in the bed. This guide will guide you through all the steps needed to turn your balcony into a strawberry paradise. From the right location to the perfect balcony box right through to professional care, you will find out all the important details. A handpicked list of ideal varieties will show you the way to your own strawberry snack garden on the balcony.

Growing Instructions

The successful cultivation of strawberries in flowers is based on an interaction of important single factors. Therefore please pay attention to all sections of this manual, because sometimes it just lacks little things, if the hoped-for harvest fails.

Cultivation by sowing

Instead of buying ready-drawn strawberry plants, the cultivation for the ambitious home gardener begins with the cultivation. Certified seeds are available from specialist retailers. Alternatively, harvest the fine seeds yourself. To do so, dry fully ripe fruits and collect the seed nuts from the outer skin. Until the sowing date in February or March, keep the seed dark, cool and dry. How to grow strawberries for the flower box itself:
  • Soak seeds in chamomile tea or lukewarm water for 4 to 6 hours
  • Fill a seed bowl with potting soil and spray with soft water
  • Sprinkle the seeds, press with a board and sift thinly
  • Cover the seed hopper with a transparent lid or plastic wrap
In the partially shaded window area, germination takes between 2 and 6 weeks at an ideal 16 to 20 degrees Celsius. If the substrate dries, spray it with room-warm water. In the 5-leaf stage you can pique the seedlings in individual pots. Until the beginning of the planting period, the care is limited to regular watering in case of dryness.

Tips for the perfect flower box

For vigorous growth and a rich harvest, strawberries in the planter need sufficient substrate volume. As a rule of thumb, it has been proven in practice to provide each plant with 25 to 30 cubic centimeters of soil. Choose flower boxes with a width of 25 to 30 cm. The length can be adjusted to the space of the balcony. With 60, 90 or 120 cm long balcony boxes every garden center is well stocked.
When buying, please make sure that a flower box has several bottom openings, so that here excess rainwater and irrigation water runs off. Rounded edges prevent the tendrils of your strawberry plants from bending. Advantageous are planters with integrated irrigation system. Here is a supply of water in a separate level, from which you can use your thirsty plants. When the stock is to be replenished, can be read on the water level indicator.
Tip: Window boxes in dark colors attract the sun, whereupon the substrate with the root ball can heat up strongly in midsummer. The better choice are therefore planters in white or light pastel tones, because here the sun's rays are reflected.

Substrate - mixing yourself is the trump card

The own cultivation of strawberries in the flower box offers not least the advantage that you later know exactly what the fruits contain and what not. Pre-fertilized potting soil from the discounter nullifies this privilege. By mixing potting soil for your strawberries, you pave the way for a premium-quality strawberry harvest. That is how it goes:
  • Use organic vegetable soil without peat as base
  • Tire, sieved compost under the bio-substrate mix in the ratio 1: 3
  • Add about 100 grams of horn shavings per flower box
  • A few handfuls of perlite, expanded clay or lava granules for optimized permeability
If you do not have your own compost heap, you will find ready packaged products in the trade. Alternatively, add a Bio-Langzeitfertilizer for berry plants to the substrate, such as the innovative organic fertilizer with sheep wool from Compo. The nutrients bring growth and flowering from the start into motion. A one-time bonus is usually enough for the entire season.

The expert planting technique is based on important aspects, such as correct planting depth, appropriate planting distance and the prevention of damming water in the substrate. When the first warm sunrays lure in the beginning of April, the strawberry plantation time begins on the balcony. This is how you proceed correctly:
  • Put the potted plants in water to soak the root ball
  • On the box floor lay a layer of expanded clay, gravel or potsherds as drainage
  • Lay a breathable fleece over it, so that the water-bearing layer does not get muddy
  • Fill the substrate so that a pouring edge is exposed
  • Populate strawberries and plant at intervals of 20 to 30 cm
It is important to note that the planting depth should be such that the heart bud is just above the surface of the earth. Firmly press the substrate with both hands for a good ground connection. First carry the finished planted strawberry box to its location and then water.
Tip: In order for the loose substrate mixture to settle, it is filled into the balcony box about 2 to 3 weeks before planting. This precaution prevents the root bales of freshly planted strawberries from being partially exposed after some time and soil needs to be replenished.

Location

Strawberry blossom

A sunny, warm and luftumspülte location at the south-exposed location brings you on the balcony a strawberry harvest in the best quality. In half shady place thrive the frugal plants also. However, the abundance of flowers and the fruit hanging leave a lot to be desired.

Pour and fertilize

One of the key functions of care is the consistent supply of water. On hot summer days please check in the early morning and again in the evening if the soil has dried. Run the water from the watering can directly onto the substrate until it runs out of the bottom openings. The next time it is watered only when the surface of the earth has dried noticeably. Field trials in professional strawberry cultivation have proven that the best time to water in the early morning is between 3 and 4 o'clock.
Those who do not like to get up so early provide their strawberry plants on the balcony in good time, before the sun hits the leaves directly. If you follow our recommendation for a nutritious substrate mix, additional fertilizer applications are not required in the first year. Only when the leaves are light green to yellowish and indicate nutrient deficiency, administer a liquid organic fertilizer for berry plants. In the following years you provide strawberry plants on the balcony from April to September every 3 to 4 weeks with an organic plant fertilizer, which you add to the irrigation water.

Mulching keeps strawberries clean and healthy

In the flower box, strawberries seldom come into contact with the substrate. Rather, the long tendrils dangle elegantly over the edge. Where there are still points of contact between the fruits and the soil, lay out a mulch layer of straw. This simple trick keeps strawberries clean and prevents them from rot and mold.

Cutting after the harvest

Depending on your choice of variety, the harvest extends into October. When the strawberry season ends on the balcony, cut back the plants. To do this, remove all leaves and tendrils except for the heart bud. With this cutback you eliminate accumulated inhibitors, which could affect another strawberry time on the balcony.

Wintering - Tips & Tricks

Strawberry plants are hardy, so they thrive in the flower box perennial. Experience has shown that they maintain their vitality for at least two to three years before they are exhausted in the fourth year. Since the root ball behind the thin walls of the balcony box are in an attackable position, we recommend this winter protection:
  • Place the planter in a wind and rain proof niche after cutting
  • Put a wooden or styrofoam underlay
  • Wrap the vessel in bubble wrap
  • Pull a coconut mat over the foil, which projects beyond the edge of the box 10 cm
  • The substrate cover with leaves, wood wool or straw
If it comes to winter damage to strawberries in the flower box, drought stress is the most common cause. Therefore, continue to water the plants so that the soil does not dry out.
